In this paper a theoretical model for transient behaviour analysis of the discharge current pulse in the transversely excited atmospheric pressure CO2 laser with dielectric corona pre-ionization is presented. The laser discharge tube is modelled by a non-linear distributed RLC electric circuit. The transmission line method is applied to the non-linear distributed circuit and it is approximated ...

By "listening to photons," photoacoustics allows the probing of chromosomes in depth beyond the optical diffusion limit. Here we report the photoacoustic resonance effect induced by multiburst modulated laser illumination, which is theoretically modeled as a damped mass-string oscillator and a resistor-inductor-capacitor (RLC) circuit. Through sweeping the frequency of multiburst modulated lase...

The latency insertion method (LIM) is a transient simulation technique for circuits and is based on a finite-difference formulation, like the well-known finite-difference time-domain (FDTD) method for solving Maxwells equations. The LIM, like the FDTD method, is only conditionally stable resulting in an upper bound for the time step of the transient simulation. This bound on the time step is a ...

The UMTS 3G system (3 rd generation cellular system) is designed to offer a packet switched mode for data transfers in parallel to a circuit switched mode. This feature was planned since the beginning of 3G studies, contrary to 2G ones (such as the GSM system). To provide reliable data transfers, protocols implementing ARQ (Automatic Repeat reQuest) techniques are needed. In UMTS, up to three A...

Minimization of power loss in the tuning circuits of frequency-tunable small resonant antennas, such as microstrip patches, is studied. First, the frequency shift and the associated power loss in certain tuning circuits are theoretically calculated based on approximate circuit models of fairly narrow-band resonant antennas. By investigating the ratio of frequency shift and loss, an optimal conf...

For digital system designs the propagation delays due to the physical interconnect can have a significant, even dominant, impact on performance. Timing analyzers attempt to capture the effect of the interconnect on the delay with a simplified model, typically an RC tree. For mid-frequency MOS integrated circuits the RC tree methods can predict the delay to within 10 percent of a SPICE simulatio...

1. First, wire up the circuit as shown in the diagram above, with the resistor, inductor, and capacitor connected in series to one another and the signal generator. Use the output of the Science Workshop 750 as the signal generator. 2. Start with the following values for resistance, inductance, and capacitance: • R = 500 Ω; L = 100 mH = 0.1 H; C = 1 μF = 1 x 10 F 3. Throughout the experiment yo...

In this paper, a closed form delay and power model of a CMOS inverter driving a resistive-inductive-capacitive load is presented. The model is derived from Sakurai’s alpha-power law and exhibits good accuracy. The model can be used for the design and analysis of the CMOS inverters that drive a large interconnect RLC load when considering both speed and power. Closed form expressions are also pr...

We propose an resistors, inductors and capacitors (RLC) electrical circuit to theoretically analyze fully simulate a new type of non-Hermitian Su-Schrieffer-Heeger (SSH) model with complex hoppings. formulate its construction investigate properties by taking advantage the circuit’s versatility. Rich physical can be identified in this system from normal modes oscillation RLC circuit, including h...
